A telescoping mast apparatus has a plurality of nesting cylinders. The telescoping mast apparatus has a plurality of telescoping cylinders and a plurality of straps. The plurality of cylinders is extendable from a base. Each strap extends from near a bottom of an outer cylinder, around an upper roller near a top of the outer cylinder, and is attached near a bottom of an inner cylinder. The plurality of straps and the plurality of telescoping cylinders intercouples in series with alternating straps and cylinders. The plurality of cylinders is extended by retracting a first strap from the outer cylinder, which raises an intermediate cylinder, which retracts the intermediate strap from the intermediate cylinder, which raises the second intermediate cylinder.
